Question

In humans, at the end of the first meiotic division, the male germ cells differentiate into the

• A. spermatids
• B. spermatogonia
• C. primary spermatocytes
• D. secondary spermatocytes

Answer 1

The correct option is D secondary spermatocytes

During embryonic development, the primordial germ cells migrate to the testis where they become spermatogonia. At puberty, the spermatogonia proliferate rapidly by mitosis. Some undergo growth phase to become primary spermatocytes that further undergo through meiotic division I to become secondary spermatocytes. After the completion of meiotic II, the secondary spermatocytes produce spermatids which differentiate to form spermatozoa.
